1. 6. Torque-Based Load Estimation for Passenger Vehicles

   Master-uppsats, Linköpings universitet/Reglerteknik

   Författare :Tobias Nyberg; [2021]
   Nyckelord :Load Estimation; RLS; Recursive least squares; torque; torque-based; mass estimation; mass; passenger vehicle; estimation algorithm; load estimation algorithm; forgetting factor; RLS with forgetting factor;

   Sammanfattning : An accurate estimate of the mass of a passenger vehicle is important for several safety systems and environmental aspects. In this thesis, an algorithm for estimating the mass of a passenger vehicle using the recursive least squares methodis presented. LÄS MER

3. 7. The relation between rolling resistance and tyre temperature in real driving scenarios

   Master-uppsats, Linköpings universitet/Fordonssystem

   Författare :Hugo Jansson; Martin Åsenius; [2021]
   Nyckelord :tyre; tire; model; temperature; brush model;

   Sammanfattning : A large portion of the world’s total emissions is caused by the transport sector where rolling resistance is one of the contributing factors. The inner tyre temperature is a factor that greatly influences the rolling resistance. LÄS MER

4. 8. Monitoring energy efficiency of heavy haul freight trains with energy meter data

   Master-uppsats, KTH/Spårfordon

   Författare :Philipp Geiberger; [2021]
   Nyckelord :Energy consumption; Energy meter; Energy monitoring; Heavy haul freight train; Key performance indicator; Multi-particle model; Simulation; Energiförbrukning; Elmätare; Energiuppföljning; Tungt godståg; Nyckeltal; Flerpartikelmodell; Simulering;

   Sammanfattning : In this MSc thesis, it is investigated what parameters are relevant for describing energy consumption of heavy haul freight trains and how these can be used to develop key performance indicators (KPIs) for energy efficiency. The possible set of KPI is bounded by data available from energy meters used in electric IORE class locomotives hauling iron ore trains in northern Sweden. LÄS MER

5. 9. Analysis of the energy consumption of the powertrain and the auxiliary systems for battery-electric trucks

   Master-uppsats, KTH/Fordonsdynamik

   Författare :Guanqiao Song; [2020]
   Nyckelord :Battery-electric truck; Energy consumption analysis; Battery loss; PT1 battery model; Power Take Off; Sankey diagram; Direct-Current charging; Batterielektrisk lastbil; Energiförbrukningsanalys; Batteriförlust; PT1 batterimodell; Power Take Off; Sankey diagram; Direct-Current charging;

   Sammanfattning : The electrification of the truck is crucial to meet the strategic vision of the European Union (EU) to contribute to net-zero greenhouse gas emissions for all sectors of the economy and society. The battery-electric truck is very efficient to reduce the emissions and has also a lower Total Cost of Ownership (TCO) compared to diesel trucks. LÄS MER

7. 10. Introduction of a Sustainable Alternative for Bitumen : Case study of lignin-based asphalt for the Swedish market

   Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Författare :Shkar Hashmi; Ahmed Jabary; [2020]
   Nyckelord :lignin; asphalt; bitumen; procurement; market; sustainability; lignin; asfalt; bitumen; offentlig upphandling; marknad; hållbarhet;

   Sammanfattning : For some time, sustainability has been the major principle of development across the globe, and all aspects of society are somehow affected by the concept. Companies are faced with stricter regulations and are forced to look for solutions to reduce their environmental impact. LÄS MER
